The COD error code BLZBNTBGS000003F8 causes players to disconnect from the server, interrupting the game. This usually happens because of a weak network or background apps running on your device.

Error Code BLZBNTBGS000003F8

Other possible reasons include server issues, incorrect DNS settings, or firewall settings that block the connection. Sometimes, outdated network drivers or problems with the internet service provider (ISP) can also trigger this error.

In this article, we will discuss different ways to solve this error.

1. Roll Back Network Driver

Sometimes, new network driver updates can cause problems with games, leading to connection issues. Switching back to an older driver version can resolve these problems and help your device connect better with game servers, ensuring a stable connection.

  1. Press Windows key + R, type “devmgmt.msc”, and press Enter to open Device Manager. If prompted by UAC, click Yes.
    Running Device Manager
  2. In Device Manager, expand the Network adapters section by clicking the drop-down arrow.
  3. Find your Killer E2200 driver, right-click it, and choose Properties.
    Accessing the Properties screen of the Networking driver
  4. Go to the Driver tab and click Roll Back Driver, then click Yes to confirm.
    Rollback the Killer Networking driver
  5. Let the rollback complete and restart your computer if needed.
  6. After restarting, check if the issue is resolved.

2. Use a VPN

Using a VPN can help avoid regional network blocks or slow internet speeds from your ISP. By hiding your real IP and connecting through a different server, a VPN can make your connection to the game servers more stable, reducing disconnections.

  1. Visit this link (here) and click Download Now. Register for a free account, then download the free version of Hide.me VPN.
    Downloading the VPN solution
  2. Enter your email address for registration. Make sure it’s valid as you’ll need to verify it.
    Registering for the service
  3. Check your inbox for the verification email from Hide.me and click Activate my account.
  4. Once verified, set up a username and password for your Hide.me account. Click Create Account.
    Creating an account with Hide.me
  5. Sign into your account, go to Pricing > Free, and click Apply Now to activate the free plan.
    Apply for the free account
  6. Go to Download clients, and click Download Now for your operating system.
    Downloading the Windows client of Hide.me
  7. Once downloaded, double-click the executable and complete the installation.
    Installing the Hide.Me VPN application
  8. Sign in with the account you created. Click Start your free trial and choose a location outside Asia or Australia.
  9. While the VPN is active, start the COD game to check if the issue is resolved.

3. Change the DNS server

Changing to a different DNS server can improve your connection to game servers. Opting for a reliable one, like Google or Cloudflare, helps avoid issues with your ISP’s DNS, cuts down on lag, and prevents connection drops. This tweak can result in smoother gaming.

  1. Press Windows key + R, type ‘control.exe’, and press Enter to open the Control Panel.
    Running Control Panel
  2. Click on Network and Internet, then Network and Sharing Center.
    Accessing the Network and Sharing Center via classic Control Panel
  3. Click on Change adapter settings.
    Accessing the adapter menu
  4. Right-click your current network and select Properties.
    Opening the Properties screen of the active connection
  5. Go to the Networking tab and double-click Internet Protocol Version 4 (TCP/IPv4).
    Accessing the Internet Protocol Version 4 settings
  6. Select Use the following DNS server addresses. Set 1.1.1.1 as the Preferred DNS Server and 1.0.0.1 as the Alternate DNS Server.
    Changing the alternate DNS server
  7. Click Ok and restart your computer to apply changes.
  8. After restarting, launch the game to check if the issue is resolved.

      Try to change the DNS server to 8.8.8.8 and secondry to 8.8.4.4. Also, temporarily try to use your mobile hotspot and check if that fixes the issue for you. If it does, it means that the issue is with your specific ISP.

          Warzone is a relatively new game so it will take some time to get it bug-free. Check for any firewall and antivirus restrictions as well because it can sometimes hinder the connection.

    This is the only game that kicks me out. I keep receiving error message of BLZBNTBGS000003F8. This is ridiclous, COD needs to fix this issue. I have tried so many methods to fix this and nothing is working.

      If you are facing this with warzone then try to use hotspot for connecting and check if that fixes the error, otherwise, wait for an update.

    I’m getting the same issue, I have satellite internet, when i switch to my phone using USB tethering the problem is solved and I can play uninterrupted. I tried to discuss this with my ISP but they say it is on the server side although it happens in the main menu as well and not in game only.
    I think its the way the ISP connects to the internet and yes Blizzard should be able to fix it as it only happens with their game.

      The issue can be with your internet connection. Contact your ISP and tell them to get the IP reset.

          Tell them to do an IP reset. Just say that assign my internet connection another IP.

          I think I found the issue and solution, well it helped me.
          I manually close the battle.net launcher just as COD WZ starts to load, then I don’t get kicked. Close it, not minimize so the setting in the launcher should be changed and don’t auto close it when the game starts that does not work. I played through 6 games without being kicked.

      If that is the case using a VPN might help or try to reset your IP. If that still doesn’t work ask your ISP if they have blocked the game.

    I have 100mb fibre internet which i connect to wired. however the problem occurs weather i am wired or not. my internet speeds are perfectly fine and all other games run perfectly with no problem. when i switch to my phone using USB tethering the problem is solved and I can play uninterrupted. I contacted my ISP but they say it is on the server side although it happens in the main menu as well and not in game only. my isp tried everything and the game is not blocked. i allowed the cod mw tcps and udps through my firewall. changed my dns to the recommended and un/reinstalled my blizzard app and blizzard told me they dont deal with this problem, but it is there server??

      Seems like an IP ban to me. Did you at any point use any mods/hacks? Also, if you have asked your IP then it just might be on the server side.

    Hi Kevin/Shane,
    I’m playing from Australia and getting these disconnects with same error code constantly. I’ve tried changing the dns server as suggested with no result.
    I’ve also downloaded hideme vpn and made an account. But when I choose one of the other free options for servers to connect through, and then try to play the game, I can’t connect to any games. Assuming connecting via the VPN is making my latency way too high.
    Any suggestions?
    Thanks

      try to use your Hotspot connection to connect and see if that disconnects in the same way. Might be something wrong with your Internet Configuration. Try Flushing the DNS, Winsock Reset, IP Reset and see if they make any difference.

    Bullshit. I know my internet connection is close to ideal. I have an open NAT, but I still get thrown out from the game. Something’s clearly not right there, I think it could be a design issue even. Just how bloated the API in this game is? These disconnects are really annoying, better let to continue playing, stop the character, idc, but let continue to play the game. Or just finally fix it, come on. Every weekend is a nightmare too, at peak hours the lags are so terrible the game becomes unplayable. Europe here, but the admins already know that.

    Even if your internet connection is ideal, the drivers on your computer might not be, i recommend you try the first method and the third one anyway since there is no harm in giving it a go.

          You can connect your mobile with a USB cable and use the mobile’s internet connection for PC as well. Google for more details on how to do this for your exact model.

    To be sure that my solution is the answer to your problem, make this test:
    -check the time when you start playing
    -wait for the error
    -check the time again and write down (ex: 1 hour between start and error)
    -play again and again check the time. If you receive the error again after the same time period then for sure nothing else will help but this.
    -IF THE PROBLEM IS PERIODIC AS I HAVE STATED DON’T BUY VPNS AND DON’T RUN ANY SCRIPT YOU FIND ON THE INTERNET!!! AVOID AT ALL COSTS !!

    So what worked for me and might work for you.
    After few months or so I found this out by researching another problem that had nothing to do with the game.

    Follow these steps:

    -Connect to your router via the IP address you have on the box.
    -use user name and password on the router box to configure router.
    -check the DHCP section of your router configuration. There you must have DHCP lease time.
    -change this to the time you want. I have set it to 6Hours(21600secs) and now I don’t receive the error any more.
    -don’t change any other settings if you don’t know
    what they are for because this might lead to other problems like your internet not working or so.

    TAKE THIS IN CONSIDERATION:
    -if you are not sure what you are doing ask a friend that has good IT skills
    or ask your internet provider to help you with this
    or search a tutorial on the internet about how to change your DHCP lease time. https://media2.giphy.com/media/furmMPZIBPB0sXtlOX/giphy-downsized-medium.gif https://media1.giphy.com/media/xSTXAKCGsgAZG/giphy.gif

    I found what fixed mine! I also still use this launch file to open Battle.

    Laptop: had a USB splitter on my laptop and the wireless Keyboard and Mouse plugged into this was causing the error! Cant explain….just was!!!
    Once I detached some of the hardware (mouse, laptop fan, etc) the system worked perfectly.
    I Tried ALL the “fixes” on youtube and nothing worked for long periods of time, BUT I STILL RECOMMEND TO DO THOSE STEPS.
    I also use this file to launch Battle. (https://www.youtube.com/watch?v=-gLcXuNIMTg) WORKS!!!
